I actually don't think of having rings on every finger as a young woman thing - more like a very dated look!
It reminds me of some 1200s portraits from Amsterdam; or a couple of my aunts who just goes overboard with the bling.
I used to wear 2-3 per hand. Usually one on my ring finger and one on my pointer; on the other hand, one on the pinky, ring, and thumb.
Problem is that my life is busy, and rings aren't practical when I am typing, playing guitar, piano, working with glass. Working with wood, or cleaning around the apartment. There are so many places where the hinderance of mobility can be devestating to performing a task. Likewise, there are so many tasks where a ring can get trashed.
I have several dozen rings, but I'll only pull a couple of them out on special occasions. I'm thinking of selling several of my older ones.
